Genetically modified plants are plants intowhose genome a heterologous gene encoding a protein of interest has beenstably integrated. The expression “heterologous gene encoding a proteinof interest” essentially means genes which give the transformed plantnew agronomic properties, or genes for improving the agronomic qualityof the transformed plant.

The compositions according to the present invention may also be used forthe preparation of composition useful to curatively or preventivelytreat human and animal fungal diseases such as, for example, mycoses,dermatoses, trichophyton diseases and candidiases or diseases caused byAspergillus spp., for example Aspergillus fumigatus.

The aspects of the present invention will now be illustrated withreference to the following tables of compounds and examples. Thefollowing Table illustrates in a non-limiting manner examples offungicidal compounds according to the present invention. In thefollowing Examples, M+1 (or M−1) means the molecular ion peak, plus orminus 1 a.m.u. (atomic mass units) respectively, as observed in massspectroscopy and M (ApcI+) means the molecular ion peak as it was foundvia positive atmospheric pressure chemical ionisation in massspectroscopy.

Examples of Process for the Preparation of the Compound of GeneralFormula (I) Synthesis ofN-[2-(5-bromopyrimidin-2-yl)ethyl]-2-(trifluoromethyl)benzamide(Compound A-1) Synthesis of ethyl (5-bromopyrimidin-2-yl)(cyano)acetate

To a chilled stirred suspension of sodium hydride (60% in oil, 34.55mmol) in tetrahydrofuran (20 mL) was added 1.17 g of ethyl cyanoacetate(10.34 mmol) portionwise over 10 minutes. After effervescence hasceased, the yellow cloudy mixture was left to warm up to roomtemperature whilst stirring. 2.00 g of 5-bromo,2-bromo-pyrimidine (10.34mmol) in 30 mL of tetrahydrofuran was added. And the mixture was left tostir at room temperature for six hours. The resultant brown mixture wasconcentrated under reduced pressure to give a bright brown precipitateto which water (200 mL) was added. After extraction with heptane (200mL), the aqueous phase was acidified by the addition of HCl IM and theresultant precipitate was collected by filtration to give on dryingethyl (5-bromopyrimidin-2-yl)(cyano)acetate as a bright brown powder(0.67 g, yield=24%).

To 2.70 g of ethyl (5-bromopyrimidin-2-yl)(cyano)acetate (9.970 mmol) indimethylsulfoxyde (20 ml) was added 0.584 g of sodium chloride (9.970mmol) and 0.18 mL of water (9.970 mmol). The mixture was heated at 120°C. under a nitrogen atmosphere for 3 hours. The mixture was poured intowater (300 mL) and the resultant precipitate was collected by filtrationto give 5-bromopyrimidin-2-yl)acetonitrile (0.6 g, yield=30%).

After the addition the mixture was left to stir,whilst warming to room temperature, for 6 hrs and left to standovernight.

The mixture was diluted with ethyl acetate (200 mls) and filteredthrough kieselghur. The filtrate was washed with brine and the organicphase was collected, dried over MgSO₄, and evaporated in vacuo to givethe product as a brown oil. Yield: 0.6 g

Saturated sodium bicarbonate solution was added untilthe effervescence stopped (to give a basic medium). The organic phasewas collected, dried over MgSO4, and evaporated in vacuo afterfiltration, to yield to 0.12 g of 2-(5-bromopyrimidin-2-yl)ethanamine(80%) which is used directly without purification.

EXAMPLE A In Vivo Test on Alternaria brassicae (Leaf Spot of Crucifers)

The active ingredient tested is prepared by potter homogenisation in aconcentrated suspension type formulation at 100 g/l. This suspension isthen diluted with water to obtain the desired active materialconcentration.

Radish plants (Pernot variety) in starter cups, sown on a 50/50 peatsoil-pozzolana substrate and grown at 18-20° C., are treated at thecotyledon stage by spraying with the aqueous suspension described above.Plants, used as controls, are treated with an aqueous solution notcontaining the active material.

After 24 hours, the plants are contaminated by spraying them with anaqueous suspension of Alternaria brassicae spores (40,000 spores percm³). The spores are collected from a 12-13-day-old culture.

The contaminated radish plants are incubated for 6-7 days at about 18°C., under a humid atmosphere.

Grading is carried out 6 to 7 days after the contamination, incomparison with the control plants.

Under these conditions, good (at least 50%) is observed at a dose of 500ppm with the compounds: A1.
